The Chrome XR team are proud to announce the addition of support for Augmented Reality (AR) to the WebXR API in Chrome 81, which has now rolled out to the world.

A new glTF 2.0 Interactivity Extension (KHR_interactivity) specification draft is available for public review and feedback before ratification. Using behavior graphs, this extension enables content creators to add logic and behaviors to glTF assets.
With , you can quickly preview and inspect
#meshes
and
#textures
that appear in a
#glTF
asset. It also reports details about the types, structure, and memory usage of meshes and textures.
glTF supports window glass transparency that is showcased in this broken glass window sample that demonstrates the combination of two transparency methods: KHR-materials_transmission and alphaMode:'MASK' for holes in broken glass.
Khronos is please to announce the release of three new Physically Based Rendering (PBR) material extensions for the glTF 3D asset format. The new PBR materials are refraction, color attenuation, and volumetric properties.

Khronos has released an open source glTF-Compressor tool that allows users to inspect the quality of images in a split, main UI panel with interactive slider bar to inspect and compare the original 3D asset image with the compressed version.

Create heat refraction in glTF using Transmission and Volume. The textures are animated to rotate 360 degrees in opposite directions. The thickness texture distorts whatever is behind it, so does the normal map. Get started with the pot of coals:
<model-viewer> is an open source web component that brings glTF-based interactive, accessible 3D content to your website with a single line of HTML, including AR placement on both Android and iOS.
Most renderers will not apply a bloom effect unless emission is above 1.0. To see this on a glTF model, be sure to include the KHR_materials_emission_strength extension!
Join us on October 3rd to learn how to optimize glTF through geometry, textures, and workflow. Discover cutting edge techniques to optimize your glTF content for real-time presentation.

Khronos releases glTF 2.0 in preparation of submittal to JTC 1 for international standard consideration by the ISO (the International Organization for Standardization) and the IEC (International Electrotechnical Commission).
Blender2MSFS add-on allows creation of 3D assets for
@Microsoft
Flight Simulator (2020). It is designed for
@Blender
2.83, and above. It uses Khronos' glTF 2.0 file format with multiple custom extensions and extras for special material functions.
During NYT R&D’s work developing 3D storytelling tools with the newsroom, they built plugins that fill the gap for Vite and Rollup. These plugins enable build tools to parse and optimize 3D scenes using the popular and web-friendly glTF file format.
AR on the web should be easy; no native app required. As of Chrome 81, WebXR is built-in to the web. So, now it’s easy to view glTF models in AR!
